Photometric and Image Intensified TV (IITV) measurements of auroral precipitation patterns and energy input were made at Poker Flats, Alaska in support of the 1972 ICE CAP series of rocket experiments. Photometric data was obtained on 4278A, 4861A and 6300A spectral bands using a 3-color photometer to define total energy input, proton precipitation flux, and F-region response to heat conducted energy input. A 3-beam photometer operating on 5577A, 5809A and 6300A was used to attempt to detect the presence of wavelike and/or turbulent disturbances in the D-, E- and F-regions. The IITV instrumentation operated at 4278A and 5577A wavelengths and was intended to develop high spatial and temporal resolution pictures of precipitating particle energy input.
